00:00NASA's Nancy Grace Roman Space Telescope has entered its final commissioning phase.
00:04The observatory has finished a thorough checkout of its systems and main instrument.
00:09It can now guide, take exposures, transfer data, and move between targets.
00:14The team is now fine-tuning image quality before science operations begin.
00:18Engineers worried its guidance system might struggle in crowded star fields and dusty nebulae.
00:24Test observations showed Roman performed very well in those regions.
00:28Its wide-field instrument can capture objects about 100 million times fainter than eyes can see.
00:34That is why steady pointing and sharp focus matter so much.
00:37Early tests show the telescope capturing famous sky regions in detail within short periods.
00:43Fast surveys should make large sky mosaics routine and rare sightings more common.
00:47Some systems are performing better than required, which could boost its science return.
00:53Roman is now one step closer to beginning its science mission.
